On Christmas Eve, when I was in the fifth grade and my little brother was in the first, I told him that Santa Claus would not be able to deliver gifts in the morning because he was arrested on suspicion for a series of “Toys R Us” robberies, and several drug related charges. My little brother believed me and cried all night. Even though at the time I knew it was a mean insensitive thing to do, I still laughed myself to sleep.
You could of just told him he would burn up, if he came down the chimney! did you have to say he was a thief?? LOL And I’m not shocked he didn’t put dog crap as coal in your stocking when he got older. Now that would be funny!
I though adding the prison element made my story more believable.
